Description

A coal bunker detection device Technical Field

[0001] This utility model relates to the field of coal bunker detection technology, specifically a coal bunker detection device. Background Technology

[0002] Coal bunkers are an important transit point in mining operations, used to store and transfer coal to ensure production continuity and transportation efficiency. During use, coal bunkers often experience problems such as caking, blockage, wall adhesion, and even deformation. If these problems are not detected and addressed in a timely manner, they will pose a significant safety hazard. Therefore, it is necessary to regularly inspect the internal condition of coal bunkers.

[0003] Common detection methods involve suspending a miner's lamp inside the coal bunker, with observers visually inspecting the bunker walls from above. However, due to the long distance, limited lighting and range, and the influence of rope swaying and the observer's experience, a direct and accurate assessment of the bunker's damage is difficult. Therefore, designing a coal bunker detection device for comprehensive inspection of the bunker walls is highly valuable. Summary of the Invention

[0004] The purpose of this invention is to provide a coal bunker detection device that enables high-precision detection of coal bunker wall adhesions and bunker deformation in underground mines, so as to detect potential safety hazards in a timely manner.

The module mounting plate is equipped with a main control module, a communication module, and a power supply module. The module mounting plate is placed inside the explosion-proof cover, and its two ends are fixed together with the front cover and the rear cover to form a whole. The front cover is equipped with a detection module and a multi-dimensional sensor module, and the rear cover is equipped with multiple aviation connectors and lifting rings. The detection module, the multi-dimensional sensor module, the communication module, the power supply module, and the aviation connectors are all electrically connected to the main control module.

[0006] Preferably, the detection module is a lidar, which is fixed on the front cover in conjunction with a heat sink.

[0007] Preferably, the multidimensional sensor module is a complementary inertial sensor.

[0008] Preferably, the explosion-proof cover has a cylindrical structure with connecting flange rings at both ends. The module mounting plate is placed inside the explosion-proof cover, and its ends are assembled and fixed with the connecting flange rings.

[0009] Preferably, the aviation connector includes a power connector and a network connector.

[0010] Preferably, the detection module is provided with a protective cover.

[0011] Compared with existing technologies, the coal bunker detection device of this utility model has the following advantages: it performs three-dimensional detection of the coal bunker by setting up a laser radar and a multi-dimensional sensor module, and the collected three-dimensional data of the coal bunker is sent to the host computer through the main control module and communication module for three-dimensional reconstruction and dangerous deformation identification, thus solving the problem of underground coal bunker detection with high precision and high efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As shown in Figures 1-3, the coal bunker detection device disclosed in this utility model includes a module mounting plate 1, an explosion-proof cover 2, a front cover 3, and a rear cover 4. The module mounting plate is placed inside the explosion-proof cover, and its two ends are fixed together with the front cover and the rear cover to form a complete structure. A power module 5, a communication module 6, a main control module 7, etc. are fixed on the module mounting plate. A laser detection module 8 and a multi-dimensional sensor module 9 are fixed on the front cover. The rear cover is provided with multiple external terminals 10 and a lifting ring 11 that are electrically connected to the main control module. There are two external terminals: one is a power terminal for plugging in a power cord, and the other is a network terminal for plugging in a network communication line. The power cord and the network communication line are twisted together in the lifting cable. The detection module, the multi-dimensional sensor module, the communication module, the power module, and the aviation connector are all electrically connected to the main control module.

[0017] Specifically, the module mounting plate has assembly strips 101 at both ends, the explosion-proof cover is a cylindrical structure with connecting flange rings 201 at both ends, the module mounting plate is placed inside the explosion-proof cover, the assembly strips are connected and fixed to the connecting flange rings, the front cover and the rear cover are both connected by connecting flange edges, and fasteners are used to assemble with the connecting flange rings. The assembled detection device is an integral structure, which is connected to the cable of the lifting equipment with the lifting ring to realize suspension and hoisting. When suspended, the front cover is located at the bottom, and the detection module and multi-dimensional sensor module on the front cover are located at the bottommost end, so that comprehensive detection of the coal bunker can be realized.

[0018] The detection module is a lidar. To prevent overheating and damage during use, a heat dissipation cover 12 is provided around the lidar. In addition, a protective cover 13 is provided on the outside of the lidar to prevent damage. The lidar is used by the coal bin inspection robot to detect various wear, cracks, and caking on the inner wall of the coal bin, and to accurately locate and display the specific location of cracks, wear, or caking in three dimensions. Specifically, it emits a laser signal, calculates the distance based on the time difference of the signal reflected back from the coal bin wall, and then determines the angle between the coal bin wall and the robot by the angle of the emitted laser, thereby obtaining the position information of a point on the coal bin wall.

[0019] The multi-dimensional sensor module consists of complementary inertial sensors. Since the laser sensor moves with the robot during scanning, high dynamic levels can lead to distortion of the laser point cloud. The inertial navigation system, however, can measure motion information at a higher frequency, effectively calibrating the laser point cloud data. By fusing multiple complementary sensors, measurement accuracy and robustness are improved.

[0020] The coal bunker detection device disclosed in this utility model is suspended inside the coal bunker. Through the installation of lidar and multi-dimensional sensor modules, it can achieve comprehensive detection of data inside the coal bunker, providing accurate data support for subsequent three-dimensional reconstruction.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
